SODA FOUNTAIN ATTACHMENT Filed July 25, 1935' 3 Sheets-Sheet 3 MM (1% INVENTOR. BY d ATTORNEY Patented Dec. 29, 1936 UNITED STATES PATENT OFFICE- 4 Claims.

My invention relates to a. new and improved soda fountain attachment.

One of the objects of my invention is to provide an attachment to the faucet of a soda fountain, said attachment includingV a mixer which can be operated automatically by the stream of carbonated water.

Another object of my invention is to provide a device in which the mixer may be caused to opcrate, or may be caused to remain inoperative, at the will of the operator.

Another object of my invention is to provide an attachment of improved design and having a casing which is provided with notches or recesses or openings at its lower end, so that the casing can be inserted into the liquid which is being mixed, and the glass which contains said liquid can be lowered, without causing any spattering of the liquid.

Another object of my invention is to provide a device in which the casing can be caused to contact with the liquid which is being mixed and dispensed, the outside of the casing being automatically cleaned by the carbonated water.

Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above statement of the objects of my invention is intended to generally explain the same without limiting it in any manner.

Fig. 9 is a perspective view showing the inner part of the attachment.

Fig. 10 is a perspective view of the casing of the attachment.

Fig. 11 is a top plan view of the rotor.

The device comprises a casing I which can be made of any suitable sanitary and rustless metal or other material.

A rotor 2 has a cylindrical casing, in which ro- 55l tor blades 3 are mounted. Said rotor blades 3 (Cl. 22S-27) may be integral with the casing 2 and they extend from top to bottom of the casing 2.

The lower end of the casing 2 is provided with a sleeve 4, which may be integral with the central portions of the lower edges of the blades 3.

The member 4 may be a boss or projection which is bored so as to recess the lower end thereof.

The sleeve or boss 4 is removably mountedupon a shaft 5, by means of a pin 6. The shaft 5 is mounted in a bearing l, which may be integral with the sleeve 8, which ts snugly within the cylindrical portion of the casing l.

As shown in Fig. 10, said casing I has a cylindrical portion which is provided with recesses vor notches R at its lower end, and said casing I is also provided with a tapered portion la, and a top cylindrical part Ib, said top cylindrical part being internally threaded.

As shown in Fig. 2, the top cylindrical part Ib of the casing I is provided with an internal shoulder 9, and it has internal threads which are spaced from said shoulder 9.

Referring to Fig. 9, the shaft 5 is provided with a supplemental bearing 'la at the bottom of the casing 8. A stirrer S is removably connected to the lower end of the shaft 5. For example, and as shown in Fig. 2, the lower end of the shaft 5 may be externally threaded, and the stirrer S may be provided with an internally threaded bore.

The external diameter of the casing 8 is somewhat greater than the external diameter of the casing 2,

When the parts are assembled, the casing 8 fits snugly and with a certain frictional t, within the cylindrical portion of the casing I.

The exterior casing I is provided with a shoulder I0, which acts as a stop when the casing 8 and its assembled parts are inserted.

When the parts are assembled, the rotor casing 2 is slightly spaced from the internal cylindrical bore of the adjacent part of the outer casing I.

Fig. 1 shows an ordinary nozzle or faucet of the type which is ordinarily used in a soda fountain. This nozzle or faucet has a handle H which is used to manipulate the usual lever L, which controls the flow of carbonated water by means of a suitable valve, which is not shown.

Referring to Fig. 2, the faucet F is provided with the usual central outlet nozzle Il having a bore I2, and it is also provided with two supplemental outlet bores I4, of the usual type. This faucet is of standard construction and it needs no detailed description.

The nozzle I I is used for producing the flow of a thin stream of carbonated water, under high pressure. The outlet bores I4 are used for producing a larger ilow of carbonated water. Said nozzle II and said bores I4 are connected to the same source of carbonated water under pressure. The nipple I5 reduces the effective pressure of the outflowing carbonated water which is supplied through bore I4.

The interior wall of the central nozzle II is threaded, and the supplemental nipple I5 is provided with a boss I5a, which is screwed into the lower end of the nozzle o-r tube II.

Referring to Figs. '7 and 8, said boss I 5a is provided with a central vertical passage I 6a, which communicates withl a lateral bore I6 and said lateral bore I 6 communicates with an inclined bore I'I, which extends to the bottom of the nipple I5.

'I'he outer end of the bore I6 is closed b y means of a skirt I8, which is forced over the exterior vertical surface of the nipple I5. Said skirt I8 extends completely around the outer cylindrical surface of the nipple I5.

Hence, the stream of carbonated water under high pressure is caused to iiow out of the outlet of the passage I'I, which is in the bottom of the nipple I5, and in a direction which is inclined about v45 to the vertical axis oi' the nipple I5.

In orderto form the passage I'I, the nipple may be cut by, means of a suitable tool so as to form` the planar opening or cut I9. However, the skirt I8 closes the top branch and the lateral branch Vof said cut or recess I9,vso as to restrict the flow ofthe carbonated Water, as previously described.

The lever L can be manipulated soas to cause the carbonated water to flow either out of the opening I2 or out of the openings I4.

When the carbonated water flows out of the bore or opening I2, the high pressure stream strikes the vanes 3 at an angle, thus causing therotor and the stirrer S to turn at high velocity, which may be as high as 2000 revolutions per minute.

'Ihe path of the water is indicated by the arrow-line A, in Fig. 4.

Fig. 4 shows the position of the handle H and of the Vlever L, when the central high-pressure stream of carbonated water is used.

When the handle H and the lever L are in theV position shown in Fig. 1, the carbonated water, whose pressure is reduced by the nipple I5, flows vertically through bores I4, and it will not actuate the vanes 3. The-water which flows vertically out of the bores I4 flows vertically through the annular pocket which is provided between the nipple I5 and the adjacent inner wall of the casing I, and said carbonated water then flows vertically between the vanes 3. This is indicated by the arrows in Fig. 2. If desired, the outer casing I may be provided with any desired number of lateral and upwardly inclined perforations 22.

The casing I is associated with a skirt 23, having an annular top flange which is clamped between the corresponding annular wall of the faucet F, and the top of the casing I.

`The internally threaded top of the casing I is screwed on to the correspondingly threaded ilange of the faucet F. Some of the water passes upwardly through the openings 22, and this portion of the Water fills the pocket between the top of the casing l, and thev inner wall of the skirt 23, and said carbonated` water is caused to flow downwardly along the exterior of the casing I. Hence the inside and outside of the device are thoroughly washed by the water which flows out of the bores I4.

In using the device for mixing carbonated water with a syrup, the syrup is rst put into the glass, and the glass is raised until the stirrer S contacts with the syrup, either at the top of the body of syrup, or at any desired level. The operator then moves the handle H to the position shown in Fig. 4, so as to release a stream of carbonated water at high pressure.

As this carbonated water enters the glass, the stirrer is operated energetically, thus producing an intimate mixture between the syrup and the carbonated water, while the water is forced into the glass. If the glass contains ice, the syrup and water and ice are also energetically stirred, thus producing an intense cooling eiect.

AfterV the glass has been substantially filled, the handle H is moved to the position shownin Fig. l, thus stopping the operation of the rotor, f

and producing a stream of carbonated water at lower effective pressure, which enters the glass, some of said carbonated water washing the exterior of the casing. Y

If desired, the handle H can be moved to the position shown in Fig. 1, While the casing is out of contact with the contents of the glass, thus effectively removing any residue of syrup, from the outside of the casing I, and from the interior thereof. Y

The recesses or notches R are preferably of V-shape or tapering shape, and they form an important feature of the invention, if the openings 22 and the skirt 23 are omitted, as they may be. i i

When the supply of'carbonated water is shut off,'a vacuum would be formed within the casing I, if the lower end of said casing were continuous and below the top of the contents of the glass. If the glass were then lowered, the vacuum would be broken when the bottom of thecasing lost Contact with the liquid in the glass, and this breaking of the vacuum would tend to cause the liquid to spatter. The notches or openings or recesses R break the vacuum effectively so as to eliminate said spattering.

The attachment can also be used for dispensing ice cream sodas and all varieties of mixed beverages.

The rotor blades 3 throw the carbonated water against the wall of the surrounding casing, so

that the water flows downwardly in the form of a thin annular sheet, with little or nov direct contact with the stirrer S, thus eliminating spattering. This is important if an attendant operates the device without having a glass around the lower endof the device. The stirrer can mix the contents of the glass by means of the notches R. However the casing I acts as a shield to prevent any contact between stirrer S and the glass.

I have shown a preferred embodiment of my invention but it is clear that numerous changes and omissions can be made without departing from its spirit.
